As posted on the Chicago forum, WSCR has turned off their HD. I have been checking the past couple days and it appears that is the case. Might be a good chance for DXers in the Chicago area to monitor the adjacent frequencies.
With WSCR HD off it appears that there is no AM Chicago station that is currently running HD.
